T0 all whom it may concern:

Be it known that I. HENRY WEBER, a citizen of the United States, residing at Chicago. in the county of Cook and State 0f Illinois. have invented certain new and useful Improvements in Vork-Guides for Stitchingr or Stapling Machines, of which the following; is a specification.

This invention relates to improvements in worii guides for stitchingr or stapling ma' chinos for directingr and insuring the proper positioning: ol' the work with respect to the stitching( or stapling mechanism.

further object is to provide an improved device et this character which will be simple, durable and cheap in construction. ono which may be readily attached to the machine and as readily removed, and which will be eli'ective and efficient in operatien.

To the attainment of these ends and the accomplis iment of other new and useful objects as will appear, the. invention consists in the features of' novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating an embodiment of the invention, and in which- Figure 1 is a top plan view of an improved device of this character constructed in accordance with the principles of this invention and showing the same as applied t0 the work supporting table or arm of a stapling machine. Fig. 2 is a front elevation of Fig. 1. Fig. 3 is an enlarged detail view in elevation, showing the manner of attaching the work supporting table to the main support or arm. Fig. 4 is a sectional view on line 4--4 of Fig. 1. Fig. 5 is ay detail sectional view on line 5-5 of Fig. 1. Fig. 6 is a detail sectional view on line 6-G of Fig. 1, showing a. box or casing in position to be stapled or stitched.

Fig. 7 is a sectional view on line 7-7 of Fig. 1. showing a portion of the box or case 1n position.

Referring` more particularly to the drawings and in the present exemplification of the invention, the numeral 10 designates the main support. to which is secured a Work supportingr arm or member 11. This arm or member 11 is adjusted laterally with respect to the support 10 by means of a suitable adjusting device 12. whereby the working,r support or arm may be positioned with respect to the stapling mechanism designated generally by the reference numeral 13 in Fig. 2.

All ot the above mentioned parts may be of any desired construction and 4term no part of the present invention, but constitute the subject-matter of a separate application.

The work support or arm 11 is provided with a plurality of laterally projecting studs or bolts 14, which may be arranged in any desired position with respect to the length of the arm, and are adapted to be engaged by portions of brackets 15, which latter are provided with key-hole slots 16, through which the heads of the bolts 14 pass and are secured to platforms or table sections 17. These platforms or table supports are so arranged that when secured in positirn on the arm 11 by means of the bolts 14 their upper faces will stand substantially flush with the upper face or edge ofthe arm 11, so as to form an extended support or table for the work to rest upon. The table sections are provided with a plurality of bolt apertures 18, which are preferably formed in. metallic strips 19, and these strips are countersunk in the upper faces of the table sections so that their upper faces will stand substantially flush with the top of the table sections. These strips 19 are preferably arranged parallel with the arm 11 and on each side thereof. Similar strips 20, Q1 may be provided and countersunk in the face of the table sections and are arranged so as to extend across the table sections transversely with respect to the strips 19. A frage 22 is provided with rearwardly projecting arms or portions Q3, which latter are provided with slots 24, through which fasteninfry devices .25 pass so as to engage the bolt apertures 18 in the strips 19. This gage 22 extends transversely with respect to the arm 11, and may he adjusted longitudinally with respect to the arm by looseningr the fastening devices 25. After adjustment, the gage may be secured in its adiusted position by tightening the fasteningr devices.

IThis gage is also preferably provided with a rearwardly projecting portion 26, which is n'rooved as at Q7.

The work guide comprises a guide support Q8. which is preferablv in the form of an arm. One extremity of this arm is fastened by means of a suitable fastening 29 in a recessed portion 30 of the Work support 11, and the body portion 28 thereof is adapted to be seated in the groove or recess 27 in the gage 22. This guide support may be of any desired length, and the free end thereof is' olf-set or deflected laterally as at 31. The free extremity 32 of the off-set or laterally projecting portion 31 is again deflected as shown, so as to stand substantially parallel with the body portion of the guide support. The. work guide support or arm and the deflected extremities 31 and 32 thereof are held in position in such a manner as to be spaced above the table, and secured to the free extremity 32 of the guide support is a guide 33 over and upon vvhich the work passes and rests, provided with a flangev 34 along one edge thereof to form a vertical guiding web. This guide 33 is arranged transversely with respect to the supportll and substantially parallel with the gage 22 with the flange or wall 34 disposed in a* direction toward the free end of the Work support 11. The flange or Wall 34 is deflected as at 35 to form a .rounded portion, and the guide 33 is supported from the body portion 28 preferably by means of aplate or member 36, which is secured as at 37 to the flanged portion or wall 34 so as to be spaced above the guide, as shown more clearly in Fig. 6. The plate or member 36 is secured as at 38 to the extremity of the deflected portion 32 of the guide support or arm 28. The plate or member 36 is secured to the guide 33 at a point intermediate the extremities thereof and the flange or wall 34 terminates adjacent the end of the plate or member 36 ata point remote from the end 39 of the guide 33; The free extremity of the end 39 is provided with a clenching portion 40 for clenching the legs of the staple after it is inserted into the box or case.

By properly positioning the guide above the' surface of the Work support, it will be apparent that when the box or ease 41 is placed upon the Work support, its edges Will he guided and properly positioned with respect to the stapling mechanism.

In use the box or. case 41 (see Fig. 6) being folded in the usual manner. that is, so that the Wall 42 thereof will fold under the wall 43, the box may then be placed upon the Work support so that one edge will strike the gage 22, (the latter being first properly adjusted with respect to the guide 33.) lVhen in position, the lower-most portion 41 of the box will rest upon the Work support and the edge of the wall 42 will rest upon the guide 33, While the edge of the wall 43 will pass over the plate or member 36 as the box or case is fed to the s'tapling mechanism. lith this improved construction it will be apparent that when the box or case is placed upon the work support. the edge 'The edge of the wall of the Wall 42, or rather the corner thereof, will strike the rounded portion 35 of the vertical web 34, and during a further movement of the box or case toward the stapling mechanism the edge of the vvall 42 will engage the wall or flange 34 and-be guided thereby, at the same time shoving another end of the box or case against the gage 22. will then pass under the plate or member 36, and the edge of the wall 43 will pass over the plate or member 36. As the box or case is advanced to the stapling member, the faces of the Walls 42 and 43 along their edges will rest against each other, as shown in Fig. 7, and will be positioned so that a staple or fastening device may be inserted through the overlapping portions at a point above the elenching portion 40 of the guide.

`With this improved construction it will be aiiparent that the work will be properly positioned to insure the proper insertion of the staple through the overlapping portion.

tibviously when boxes or cases of varyingl sizes are to be fastened or stitched the gage 22 may be adjusted toward or away from the flange or wall 34 and the guide 33. It will also be apparent that when desired the table sections `17 may be readily detached and the guide may also be as readily detached.

In order that the invention might be fully understood, the details of the foregoing embodiment thereof have been thus specifically described.
